Soil Profile Descriptions – As required by 25 Pa Code § 73.14(3) “…A description of the soil profile shall be recorded on the site investigation and percolation test report form for onlot disposal of sewage issued by the Department.” This specifically requires the use of the Site Investigation and Percolation Test Report for Onlot Disposal of Sewage (#3850-FM-BCW0290A) for each individual soil probe. The Department routinely receives soil profile descriptions from consultants that use their own version of the form or include information for multiple soil probes on a single form. This is an unacceptable use of the Department’s form. Modified or improperly utilized forms will not be accepted by the Department, so please dispose of any modified forms; you can obtain the latest version of Department forms from your Department of Environmental Protection Regional Office or the Department’s eLibrary website.
